Science & Mathematics

The Museum's collections hold thousands of objects related to chemistry, biology, physics, astronomy, and other sciences. Instruments range from early American telescopes to lasers. Rare glassware and other artifacts from the laboratory of Joseph Priestley, the discoverer of oxygen, are among the scientific treasures here. A Gilbert chemistry set of about 1937 and other objects testify to the pleasures of amateur science. Artifacts also help illuminate the social and political history of biology and the roles of women and minorities in science.

The mathematics collection holds artifacts from slide rules and flash cards to code-breaking equipment. More than 1,000 models demonstrate some of the problems and principles of mathematics, and 80 abstract paintings by illustrator and cartoonist Crockett Johnson show his visual interpretations of mathematical theorems.

This engraving shows a celestial globe, a terrestrial globe, and an armillary sphere, each supported on a mount decorated with caryatids. The signature refers to John Baptist Homann (1664-1724), a German engraver who established an influential cartographic house in Nuremberg in 1702. Johann Gabriel Doppelmayr, a professor of mathematics who worked with Homann on several astronomical projects, may have had a hand in the creation of this image.

Robert Hinshelwood (1812–after 1875) of New York City engraved this copper printing plate after a drawing by Expedition Naturalist Titian Ramsey Peale. The image depicts the Ptilonopus Perousei (now Many-colored Fruit Dove, Ptilinopus perousii Peale [S. polynesia]). The engraved illustration was published as Plate 33 in Volume VIII, Mammalogy and Ornithology, by John Cassin, 1858.

The engraved illustration was published as Plate 34 in Volume VIII, Mammalogy and Ornithology, by John Cassin, 1858.

William H. Dougal (1822–1895) of New York and Washington, D.C. (after 1844) engraved this copper printing plate after drawings by William E. Hitchcock.

The engraved illustration was published as Plate 35 in Volume VIII, Mammalogy and Ornithology, by John Cassin, 1858.

William H. Dougal (1822–1895) of New York and Washington, D.C., (after 1844) engraved this copper printing plate depicting four species of fish documented by the U.S. Exploring Expedition. The illustrations were to be published in Volumes XXII and XXIII, Ichthyology, by Louis Agassiz. Dougal engraved 26 of the 28 plates for this volume which was never printed.

William H. Dougal (1822–1895) of New York and Washington, D.C., (after 1844) engraved this copper printing plate depicting three species of shark documented by the U.S. Exploring Expedition. The engraved illustrations were to be published in volumes XXII and XXIII, Ichthyology, by Louis Agassiz. Dougal engraved 26 of the 28 plates for this volume which was never printed.

William Dougal (1822–1895) of Washington, D.C. engraved this print of “Nematogenys inermis [Grd]” from an original sketch by John H. Richard (c.1807–1881) of Philadelphia. The illustration was published in 1855 by A.O.P. Nicholson in Washington, D.C. as Plate XXXII in the “Reptiles, fishes, crustacea” section of volume II of The United States Naval Astronomical Survey to the Southern Hemisphere, written by Charles Girard (1822–1895).

William Dougal (1822–1895) of Washington, D.C. engraved this print of “Mastodon andium,” from an original sketch by John H. Richard (c.1807–1881) of Philadelphia. The illustration was published in 1855 by A.O.P. Nicholson in Washington, D.C. as Plate XIII in the “Paleontology: fossil mammals” section of volume II of The United States Naval Astronomical Survey to the Southern Hemisphere, written by Jeffries Wyman (1814–1874).

William Dougal (1822–1895) of Washington, D.C. engraved this print of “Belone scrulator [Grd]”, now "Strongylura marina" or Atlantic needlefish, from an original sketch by John H. Richard (c.1807–1881) of Philadelphia. The illustration was printed as Plate 13 in the “Fishes” section of the second part of volume II of the Report on the United States and Mexican Boundary Survey, which was written by Charles Girard (1822–1895). The volume was printed in 1859 by Cornelius Wendell of Washington, D.C.

William Dougal (1822–1895) of Washington, D.C. engraved this print of “Scaphiopus couchii [Baird], Ambytoma proserpina [B & G], and Ambystoma texana [Baird]”—; now Scaphiopus couchii (Couch’s spadefoot or Spadefoot toad), "Ambystoma mavortium" (Western tiger salamander) and "Ambystoma texanum" (Texas salamander); from an original sketch by John H. Richard (c. 1807–1881) of Philadelphia. The illustration was printed as Plate 35 in the “Reptiles” section of the second part of volume II of the Report on the United States and Mexican Boundary Survey, written by S.F. Baird (1823–1887).
